Question

prove that if the sides of a triangle ABC is doubled then the ratio of area of both the triangle is 1 : 4​

Answer 1

Step-by-step explanation:

Area of triangle=1/2bh

If sides doubled,

b=2b

h=2h

Area of triangle=1/2*2b*2h

=1/2*4bh

Ratio=1/2bh/1/2*4bh

=bh/4bh

=1/4

Therefore, ratio=1:4
